Hi all.I've been asked to paint a shops interior and also clean the floor.The floor is those kind of thin,lino tiles which are in a bit of a state.I've been told that they don't expect miracles,just to get the worst off.I don't have experience in this so if anyone could offer advice I'd be obliged.Would I need a machine to do this and if so could you recommend one?Could anyone give me a rough idea on pricing as well?The shop floor is about 20 foot by about 40 odd.Would I price per metre or as a whole?Thanks.
